Problems with an AT91M55800 Debugging with ULINK2

Santi Amo

Hi!,
I'm trying to debug with a AT91M55800 with an external 512KB 8bits FLASH (0x1000 0000 after remap) and an external 512KB 8bits SRAM (0x2000 0000 after remap).

I can compile de proyect and program de flash, using an initialization file to make the remap command during the flashing process --> The Flash Programing process is correct and the application is running.

But, when I try to debug the application (the initial program is very simple, only a loop with some variables) the uVision3 in about 95% of the times said me:

"Can not enter Debug Mode"
*** Error 57: illegal address (0x10000000)"

the other 5% times, the debugger starts OK.

What can I do to solve the problem?

Thanks!
